  -F prompt="A sunlit indoor lounge area with a pool" \
  -F n=1 \
  -F size="1024x1024" | jq -r '.data[0].url'

Base64 Response

curl -s https://api.openai.com/v1/images/generations \
  -H "Authorization: Bearer $OPENAI_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "model": "dall-e-3",
